The Washington Post’s newly-launched White House visitors’ database makes it clear that lobbyists remain a regular presence at 1600 Pennsylvania Ave.

But what about the GOP contenders who earlier this year competed in hopes of one day occupying the White House?

A search of the database shows that with the exception of Jon Huntsman — who served in the Obama administration as ambassador to China — the members of this year’s GOP presidential field have made few, if any, White House visits.

Huntsman visited five times from January 2009 through Jan. 31, 2012, most recently in January 2011.

At the opposite end of the spectrum are presumptive GOP presidential nominee Mitt Romney, former senator Rick Santorum (Pa.) and businessman Herman Cain, who made zero visits to the White House, according to the visitor logs.

Rep. Michele Bachmann (R-Minn.) visited twice — for the December 2009 and 2010 congressional balls.

Texas Gov. Rick Perry (R), whose full name is James Richard Perry, also visited twice in February 2011 for the National Governors’ Association meeting and for the governors’ ball.

Former House speaker Newt Gingrich (Ga.) made one visit on May 7, 2009. According to the logs, the visit was an Oval Office meeting about education.

And Rep. Ron Paul (R-Texas) visited once, on June 15, 2011, for the annual congressional picnic on the South Lawn. The logs also show a September 2011 visit by a “Ronald Paul” for a White House tour.

Correction: An earlier version of this story incorrectly stated that Jon Huntsman had visited the White House eight times. He visited five times. Two of the times originally mentioned were duplicates, while the third was a visit by Huntsman’s father, Jon Huntsman Sr.
